Abstract:
The results of electrocardiogram and coronary angiography were compared in 69 patients with acute inferior myocardial infarction(right ventricle, later wall). The sensitivity and specificity of ST segment elevation Ⅲ> Ⅱ in diagnosis of right coronary artery (RCA) as the infarction related artery (IRA) were 92.00% and 84. 21% respectively;those for ST segment depression avL > Ⅰ were 90. 00% and 89. 5% respectively. Therefore if ST-elevation Ⅲ > Ⅱ , ST-depression avL > Ⅰ and no depression on STV1 and V2 in acute inferior myocardial infarction may highly indicate that RAC be the IRA;on the contrary, the LCX be the IRA.
